The first known ransomware attack on Apple Mac computers, which was discovered over the weekend, was downloaded more than 6,000 times before the threat was contained, according to a developer whose product was tainted with the malicious software. Hackers infected Macs with the "KeRanger" ransomware through a tainted copy of Transmission, a popular program for transferring data through the BitTorrent peer-to-peer file sharing network. So-called ransomware is a type of malicious software that restricts access to a computer system in some way and demands the user pay a ransom to the malware operators to remove the restriction. KeRanger, which locks data on Macs so users cannot access it, was downloaded about 6,500 times before Apple and developers were able to thwart the threat. Still, cyber security experts said they expect to see more attacks on Macs as the KeRanger hackers and other groups look for new ways to infect Mac computers.
